A mobile terminal (104) e.g. cellular phone, has a microphone (116) and a transmission module to transmit sound signals captured by the microphone to a correspondent. The terminal (102) prevents the transmission or limits the volume of sound signals from the loudspeaker, and the terminal (104) prevents the transmission or limits the volume of the signals captured by the microphone and transmitted by the module during transaction between the terminals. Independent claims are also included for the following: (1) a transaction terminal comprising a loudspeaker (2) a mobile terminal comprising a transmission module (3) a method for controlling a transaction terminal (4) a method for controlling a mobile terminal.
